GUN LOCK.

(Application filed July 24, 1900.

(No Model.)

The object of tlii vention is to produce a; gun-'l'ock'with' as "f wpa'rts;{aspossible in wh h l 'f e parts are re a f l h, h lock pl at'e vvithout disturbing their'opera'tive relation to each other, 'a" single spring serves to actuate thehain ner"and 'the j sear, the spring is held' inits" operativeposition" by the bridle, and-in whichft-lie hamme'r is automat-. ic'ally locked from further movement after its rebound-from the firing pin, I f To this end the "invention consists in the construction, combination, and arrangement ofthepartsof a ar-1 1001;, as hereinafter fully described, "and pointed ontin thefcl'aims.

In the drawingsgfFi gure lfis'an inner face view of-a sideplate an'dthe assembled parts of'my inventionappliedthereto,the hammer being'showninits cocked positions Fig. 2 is a-plan view of 'thepa'rts seen in Fig. 1. Fig. 3 isj a fa e View similar to Fig. 1, the side plate being shown by-dotte'd lines, the hammerand tumbler s infthei'r operative position after the'rejbound' of the ham mer, and the bridleas'partly'brolgenawayi Figs. 4, 5, 1.6,and Z are"isometricperspective views of detached parts'fof'm vention, showing, repec i ely, the vma p n ga a tum ler. a ;v F 's- Sisan view of a modification, "showin g thehammer and tumbler as integral for use; in ham merle'ss guns.*,.i. l A. 1

Themeoh v odied in thisinvention consists ofa side "plate 1, a hammer 2, a tumbler 3, a locking-seagfha springj, and abridle 6, all of which parts'arejieldin their assembled position by suitabl'e fastening means, hereinafter described.

The side plate 1 and the hammer 2 may be less guns.

I of any desired form or construction, the hanimer 2-being-usually mounted on afspindle I 7, jonrnaled orotherwise movably supported on the side'pl'ate 1. "As seen in Figs; 1, 2,

and 3, the ham mer 2 is supported at the outer sideof the side plate -1, but may obviously be formed integral with the tumbler, as seen at Fig. 8, and mounted at the inner side of said plate in the manner usual for hammer- 6c The tumbler 3 isarranged at theinside of the plate 1, is secured to the spindle of the hammer 2 for controlling the movement of the hammer, and is provided with peripheral shoulders 8, 9, and 10 for engaging the sear and mainspring-in a manner presently described.

The shoulders l3 and 9 are arrangedone in advance of the other, the shoulder 8 serving v to engage the sear for holding the hammer in its cocked position and the shoulder 9 being adapted to engage the searand hold the hammer from engaging the firing-pin (not shown) after the firing and rebound of said hammer.

The shoulder 10 preferably consists of a hook-shaped extension having a rounding or beaded bearing-face for engaging the end of the adjacent arm of the mainspring, said 80,

bearing-face being rounded for the purpose of reducing friction and for rendering the firing and locking action positive and easy.

The sear 4 preferably consists of a rocking lever pivotally connected at 12 to the side plate 1 and having one end adapted to engage the shoulders 8 and 9 and its other end provided with a lateral extension 13, adapted to be engaged by a trigger (not shown) for the purpose Well known. This sear is arranged 0 to be automatically forced into engagement with the tumbler by the mainspring and is provided with a shoulder 14:, disposed between the pivotal point 12 and extension 13 or, in other words, at the side ofthe pivot 12 oppo- 5 site to the end of the sear which engages the tumbler and serves to retain said spring in its proper relative position for forcing the tumbler-engaging end into engagement with site diverging arms 15 16 are interposedbetween the shoulder 10 of the tumbler 3 and the adjacent face of the sear 4 for forcing portions of said tumbler and sear away from each other, and thereby engaging the sear 4 and shoulders 8 and 9. The arm 15 for engaging the shoulder 10 usually extends beyond the corresponding end of the arm 16 and is arranged to engage a stop-pin 17 at such time and in such a manner as to permit a free rebound of the hammer when said hammer has been released by the sear 4 for operating the firing-pin. (Not shown.)

It will be noted upon reference to Fig. 3 that the shoulders 9 and 10, stop-pin 17,'and the tumbler 3 are so relatively arranged that when the arm 15 of the spring 5 is engaged with the pin 17 the shoulders 9 and 10 are in position to simultaneously engage respectively said engaging end of the sear and the arm 15 of the spring, and when the sear is withdrawn from registration with the shoulder 8, as in firing, it is apparent that the hammer is free to move by its momentum into contact with the firing-pin and to rebound to the position seen in Fig. 3'without further resistance than its own gravity. It is also apparent that when adjusting said engaging end of the sear to give the required throw to the hammer it is simply necessary to release the sear from the shoulder 9 of the tumbler and rock the hammer forward, whereupon the end of the sear may be readily filed or otherwise fitted without removing any of the parts of the gun-lock.

The bridle 6 serves/the purpose of additionally holding the parts of the gun-lock mechanismin position and consists of a single plake having its opposite ends extended beyond the opposite ends of the spring 5 and bent at substantially right angles to its intermediate portion ard adapted to engage the inner face of the side plate 1 for holding said intermediate portion a desired relative distance from the plate 1. This bridle is held in position by suitable fastening means, as the pin 17, which preferably consists of a screw and an additional screw 20, said screws being engaged with threaded apertures in the plate 1.

The screw 20 and the adjacent ofiset end of the bridle 6 serve to additionally hold the spring 5 in position, the united ends of the spring-arms being adapted to abut against the contiguousoft'set end of the bridle.

It is evident that when desired to remove the spring 5 it is only necessary to remove the screw 20, whereupon the spring may be moved laterally from engagement with the contiguous end of the bridle and readily removed.

The operation of my invention will now be readily understood from the foregoing description and the accompanying drawings, and it will be noted that the parts are exceedingly few and simple, are readily assembled,

and form a neat, compact, and eflicient gunlock which can be manufactured at a minimum cost.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. A gun-lock comprising a lock-plate, a tumbler having front and rear shoulders, a sear for engaging said shoulders, a spring for actuating the'tu mbler and sear, and a bridle detachably secured to the plate and having one of its fastening members adapted to engage the spring and limit its action upon the tumbler at about the same time that the forward shoulder of the tumbler is registered with the-sear for the purpose described, one end of the bridle forming a stop to prevent endwise movement of the spring.

2. A gun-lock comprising a lock-plate, a' tumbler, a sear, a spring for actuating the tumbler and scar, and a bridle detachably secured to the plate and having one end form- -ing an abutment for the adjacent end of the spring for the purpose set forth.

3. In combination with a lock-plate and a bridle detachably secured thereto, and having portions thereof disposed at an angle with the main body and engaged with the plate for the purpose described, of a tumbler, scar and spring operating in the manner set forth and interposed between the plate and bridle, one of the angular portions forming an abutment for the adjacent end of the spring.

4.. A gun-lock comprising a lock-plate, a

tumbler, a sear, a spring for actuating the tumbler and sear, anda bridle detachably secured to the plate and having one end forming an abutment for the adjacent end of the spring for the purpose set forth, and a removable fastening member for holding the spring in position and permitting its removal.

5. A gun-lock comprising a lock-plate, a tumbler having front and rear engagingshoulders and a beaded projection, a soar adapted to engage said shoulders and provided with an abutting face, a V-shaped spring for ac-' tuating the tumbler and sear, said spring having one leaf engaged with the beaded projection and its other leaf abutting against the face of the sear, a bridle having portions thereof disposed at an angle with its main body and engaged with the plate, one of said portions forming an abutment for the closed end of the spring to prevent the endwise displacement of the spring, and afastening member for detachably securing the bridle and spring in position.

In witness whereof I have hereunto set my hand this 21st day of July, 1900.
